From f9234736112bf193e5ab451abbfbdf279cc53137 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 20 Aug 2007 11:38:12 -0500 Subject: [PATCH] [POWERPC] fsl_soc.c cleanup 1. Update the way get_brgfreq() finds things in the device tree. It now uses names that are less namespace polluting. The old names are supported until all boards are converted. 2. "size" is changed from unsigned int to int, to match what of_get_property() expects.
